Beyond standard dimensions: the concept of "2-ways with horn" reaches its fulfillnes.

Which is the horizon of a 2-Ways Loudspeaker?

We decided to develop something that pushes this horizon beyond imaginable. The concept of horn and 2 way was what we decided to push to the limit. We set ourselves no constraints for dimensions.

There have been several obstacles along this way and the prove that we mastered them is that the name Blumenhofer is on the Wiki.

The highlight of the loudspeaker is its absolute dynamic and finesse in the reproduction. Its complete sound stage and presentation. The feelings that it is able to deliver and evoke.

* - We think that a simple number does not reflect the actual worth and potential of this kind of speaker. The simple frequency extension cannot transmit You the emotion that this loudspeaker is able to transfer You.

Note:

In our workshop we can offer true-wood veneers.
Wood is a natural product and depending on several factors might have different color and structure. Color and structure variations of the surface are not to be considered flaws.
